Dicentra plant named ‘HORDIVAL’

ABSTRACT

A new and distinct  Dicentra spectabilis  cultivar named ‘Hordival’ is disclosed, characterized distinctive orange-red flowers, dark stems overall compact, shorter plants. The new variety is a  Dicentra spectabilis , suitable for outdoor landscape and container use.

Latin name of the genus and species: Dicentra spectabilis.

Variety denomination: ‘HORDIVAL’.

BACKGROUND OF THE INVENTION

The new cultivar is the result of a chance discovery in a garden inPrince George, British Columbia, Canada. The inventors, Lyle and PhyllisSarrazin, citizens of Canada, discovered the new variety as a naturallyoccurring chance seedling growing in a garden of the parent variety, theunpatented Dicentra spectabilis. The discovery was made in the Spring of2005.

After selecting and isolating the new cultivar, asexual reproduction ofthe new cultivar ‘HORDIVAL’ was first performed by division during theFall of 2005, in Prince George, British Columbia. ‘HORDIVAL’ has sinceproduced several generations and has shown that the unique features ofthis cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘HORDIVAL’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, day length, and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘HORDIVAL.’ These characteristics incombination distinguish ‘HORDIVAL’ as a new and distinct Dicentracultivar:

-   -   1. Dark Orange-Red flower.    -   2. Distinctive red stems.    -   3. Compact and overall shorter plant habit.

PARENTAL COMPARISON

Plants of the new cultivar ‘HORDIVAL’ are similar to the parent, in mosthorticultural characteristics. However, ‘HORDIVAL’ differs in having anover all more compact and shorter plant habit.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘HORDIVAL’ are best compared to the parentvariety.
